* TinyLoad sets the PPC timebase correctly according to your Wii's RTC. This fixes date/time issues in games.
* The video code makes lots of assumptions. It will only work if VI was left configured in a "standard" mode, with a 640x480-640x574 framebuffer. VI should be blanked; if it isn't, then TinyLoad will not blank it before launching the game so your screen will blink green for a split second as the game initializes VI. It has been tested to work correctly when launched by the Homebrew Channel in at least NTSC 480p and PAL interlaced modes. If these assumptions don't hold then the progress bar display will not work properly, but the rest of the loader should work fine.
* TinyLoad does not perform
_any_ patching of games. The lowmem video mode setting follows whatever video mode was left set by the application used to launch TinyLoad, except that PAL games are forced to PAL if NTSC is detected. This does not patch the game, it's merely the informative value in low memory; games are free to read SYSCONF/setting.txt and ignore it. I don't really care because I use 480p mode anyway. If you need more advanced options, just use Gecko OS.
* Normally, game audio will not work correctly if launched via a loader that was initially launched via BootMii-boot2. This is a bug in libogc (it doesn't know how to initialize the DSP for the first time and leaves it in a broken state), and it affects anything running after the Wii was booted first into a libogc application, including the System Menu's loader. In other words, BootMii-boot2 → HBC → System Menu (or Gecko OS) → Game may cause distorted audio. TinyLoad '''does''' work, by resetting the audio hardware to let the game reinitialize it properly. So, BootMii-boot2 → HBC → TinyLoad → Game will work fine. This ought to be worked around in a future release of HBC, at least. I'd suggest fixing libogc, but I know shagkur is just going to rip the proper code from the SDK again. Anyway, launching using TinyLoad will work fine as it contains the workaround.
* TinyLoad will load the correct IOS as specified in the partition TMD. It does not support loading any other IOS.
